Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2124, here are decompositions:
- 11 + 2113 = 2124
- 13 + 2111 = 2124
- 37 + 2087 = 2124
- 41 + 2083 = 2124
- 43 + 2081 = 2124
- 61 + 2063 = 2124
- 71 + 2053 = 2124
- 97 + 2027 = 2124
Showing the first eight; more decompositions exist.
